Abstract

Die Erfindung betrifft ein kapazitives Füllstand-Messsystem, insbesondere zur Erfassung eines Füllstandes eines Kraftstoff-Behälters in einem Fahrzeug. Erfindungsgemäß sind Messelektroden 10a, welche zusammen mit einer leitfähigen Oberfläche, z. B. des Kraftstoff-Behälters, Mess-Kondensatoren bilden, zusammen mit einer Auswertungselektronik 16 auf einem flexiblen, folienartigen Träger 20 angeordnet. Die Auswertungselektronik erzeugt ein dem Füllstand des Behälters entsprechendes Ausgangssignal, welches über eine steckerartige Verbindung verfügbar ist. Das Ausgangssignal ist mit einem in dem Fahrzeug verwendeten Bus, z. B. dem so genannten CAN-Bus, kompatibel.The invention relates to a capacitive level measuring system, in particular for detecting a level of a fuel tank in a vehicle. According to the invention are measuring electrodes 10a, which together with a conductive surface, for. As the fuel tank, measuring capacitors form, together with an evaluation electronics 16 arranged on a flexible, film-like carrier 20. The evaluation electronics generates a fill level of the container corresponding output signal, which is available via a plug-type connection. The output is connected to a bus used in the vehicle, e.g. B. the so-called CAN bus compatible.
